The main point is, what is the best way to read in strings to an array in MIPS? 要点是，在 MIPS 中将字符串读入数组的最佳方法是什么？ I'm fairly new to MIPS, so any help would be greatly appreciated! 我对 MIPS 相当陌生，因此将不胜感激任何帮助！ Nov 23, 2020 · MIPS assembly string array. asciiz "AB" is compiled into three bytes 65, 66, 0. ⬅ MIPS cookbook delicious instructions Contents: Printing strings and characters; Using (Global) Variables; Choosing registers; Doing Arithmetic; Writing functions; Printing strings and characters. globl main . Python. Also remember to allocate 1 more byte of storage than you need for the string, to hold that nul byte. Where am I going wrong?I set min originally to zero, then check if the array is less than or equal to this value and then if it is I jump to a label and make the value of min to be the value of the array, then jump back to iterating the array.
